The Rig

Baz and Garrow get closer to understanding their mission when they explore the pump control room, and realise they need Fulmer to help them – leading to painful consequences for Fulmer as he struggles to keep a grip on his sanity. When the crew's anxieties rise as a glimmer of potential hope turns sour, Magnus finds himself losing his grip as tensions amongst the group reach fever pitch.

The new arrivals on board from the Kinloch Charlie immediately make their presence felt, as Pictor head Coake enlists a group to undermine a weakened Magnus and force their way to the pump control. But when Coake's motives are investigated and the crew realise he isn't giving them the full truth, they find themselves locked in an urgent race for answers with lives at stake.
